Back in June I reset the security code and since then I haven't had any problems with the car that was until Friday. The Vat's Security System light is staying on and I can't even get my car to crank. How do I do away with this system? How long will it take?

    If you are mechanical and electrical inclined, you might check out YouTube videos, and search passlock. There is several videos on this subject with how to. Your Welcome

    I have checked out the video's and the passlock sights, tried everything but changing the module and lock cylinder. Thank you for your advice I am looking into a module that will get rid of the system forever.

    Then you need an ECM that has the feature removed from it's programming.
